For children with CP with limited movement and sensation, the risk of pressure sores increases. Pressure sores often occur on bony parts of the body. For example, pressure sores may occur when a child has limited feeling and movement of their lower body and uses a wheelchair; the tailbone bears weight when seated and can become vulnerable to pressure sores. The occupational therapist can educate the child, family, and caregivers about how to prevent pressure sores by monitoring the skin for areas of irritation, changing positions frequently, or using a tilt-in-space wheelchair. Effect of cognitive and perceptual impairments OT can address cognitive and perceptual disabilities, especially of the visual-motor area. For children with CP who have difficulty remembering the order and organization of self-care tasks in the morning, an occupational therapist can construct a morning routine schedule with reminders. An occupational therapist may analyze the steps involved in a task to break down an activity into simpler tasks. For example, dressing can be broken down into smaller, manageable steps. This can be done by having a caregiver lay out the clothing in order so the child knows what needs to be put on first. Effect of motor impairments The effect of motor impairments is significant for children with CP because it affects the ability to walk, propel a wheelchair, maintain hygiene, access the community and interact with other people. Occupational therapists address motor impairments in a variety of ways and makes use of various techniques, depending on the child's needs and goals. The occupational therapist may help the child with gross motor rehabilitation, or whole body and limb movements, through repetitive activities. If the child has muscle weakness, progressive resistance exercises can improve muscular strength and endurance. Fine motor rehabilitation, or small, specific movements, such as threading the eye of a needle, can be implemented to improve finger movement and control. For children with difficulties speaking, an occupational therapist may liaise with a speech therapist, carry out assessments, provide education and prescribe adaptive equipment. Adaptive equipment may include picture boards to help with communication and computers that respond to voice. Occupational therapists can help the child promote use of a neglected arm through techniques such as constraint-induced movement therapy (CIMT), which forces use of the unused arm by placing the other arm in a sling, cast or oversized mitt. Another OT technique that may be used is neuromuscular facilitation techniques,
